Deuteronomy 19:8-10

It is worthy remark, that this precept of forming three cities more, in case of the enlargement of Israel's borders, was never fulfilled as it respected Israel only. But, had it not an eye to the enlargement of the church, when both Jew and Gentile were brought into one? See Isaiah 54:2. And in this sense was not the precept intended to show, that the cities of refuge were as many to the Gentiles as to the Jews, and all typically referred to one and the same blessed object? Colossians 1:20.
